LOS ANGELES – Elpidio Reyna, an alleged rioter caught on video hurling large rocks at moving Border Patrol vehicles during violent protests in Los Angeles, was arrested Wednesday at the U.S.-Mexico border, authorities announced.
The attack, which took place on June 7 in Paramount, California, occurred amid anti-ICE demonstrations that spiraled into violent clashes. In video footage released by U.S. Attorney Bill Essayli, Reyna is seen wearing what appears to be a motorcycle helmet as he repeatedly throws rocks at passing Border Patrol vehicles. One federal officer was reportedly injured during the incident.
Reyna was taken into custody at the San Ysidro Port of Entry in San Diego after surrendering to federal authorities. He now faces a felony charge of assault on a federal officer, Essayli confirmed.
“This was a dangerous and reckless attack that could have killed one of our agents,” said Essayli. “Reyna’s arrest sends a clear message: You cannot assault federal officers and expect to get away with it.”
Reyna was arrested by the very Border Patrol officer whose vehicle was struck in the attack.
FBI, Federal Officials Respond
FBI Director Kash Patel condemned the assault, stating, “The FBI will never tolerate violence against those who serve and protect this nation.”
FBI Deputy Director Dan Bongino also commented on the arrest via X (formerly Twitter), writing:
“You may remember Elpidio Reyna — the subject who allegedly threw rocks at federal officers during immigration operations in June. We got him. Those who attack America’s police officers can run, but they can’t hide.”
Reyna is scheduled to appear in federal court Wednesday afternoon.
Riots Sparked Federal Response and Legal Battle
The June riots, sparked by growing backlash to ICE activity in the Los Angeles area, led to days of unrest. In response, the Trump administration deployed 700 Marines and activated nearly 4,000 National Guard troops to restore order — a move denounced by California officials.
Governor Gavin Newsom and Los Angeles Mayor Karen Bass criticized the federal deployment as an unconstitutional overreach. Newsom filed suit against the Trump administration, arguing the use of state National Guard troops violated the Posse Comitatus Act, which bars the military from performing domestic law enforcement duties.
A federal judge initially sided with Newsom, ruling the deployment exceeded Trump’s authority. However, that decision was overturned by an appeals court, leaving control of the troops with federal authorities. A final ruling is expected next month as legal arguments continue.
